DWRITE_UNDERLINE
構造体サイズ=各フィールドのバイト数(x64/x86 で異なる場合は x64/x86 と併記)。x64/x86 列=フィールドのバイトオフセット(HSPで dupptr / lpoke / wpoke 等に使用)。
フィールド
| フィールド | 型 | サイズ | x64 | x86 | 説明 |
|---|---|---|---|---|---|
| width | FLOAT | 4 | +0 | +0 | 下線の幅(線の長さ)をDIP単位で表す値。 |
| thickness | FLOAT | 4 | +4 | +4 | 下線の太さをDIP単位で表す値。 |
| offset | FLOAT | 4 | +8 | +8 | ベースラインから下線までのオフセット。正の値は下方向を表す。 |
| runHeight | FLOAT | 4 | +12 | +12 | 下線が描かれるテキストランの高さをDIP単位で表す値。 |
| readingDirection | DWRITE_READING_DIRECTION | 4 | +16 | +16 | テキストの読み進み方向を示す列挙値。 |
| flowDirection | DWRITE_FLOW_DIRECTION | 4 | +20 | +20 | 行の流れる方向を示す列挙値。 |
| localeName | LPWSTR | 8/4 | +24 | +24 | テキストのロケール名を示すNULL終端ワイド文字列。 |
| measuringMode | DWRITE_MEASURING_MODE | 4 | +32 | +28 | テキスト測定モード(自然/GDI互換など)を示す列挙値。 |

HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。
